St. Louis, MO (Sports Network) - Alexander Steen scored twice, including the game-winner with 6:34 left in overtime to lift the St. Louis Blues to a 2-1 victory over the defending champion Los Angeles Kings in Game 1 of their Western Conference quarterfinal series from Scottrade Center.

Steen scored a power-play goal in the first, and then added a short-handed tally in the extra session after Los Angeles goaltender Jonathan Quick misplayed the puck behind his own net.

Quick was pressured by Steen behind his own net and tried to play the disc off the end boards, but it bounced to the low right side, where Steen recovered it before stuffing the puck into the empty net to help the Blues draw first blood in this best-of-seven series.

Brian Elliott stopped 28-of-29 shots for the Blues, who were swept by the Kings during the conference semifinals last season and dropped all three regular-season games against Los Angeles this year.
